All about Probability
A sampling error is?
What is the natural discrepancy, or amount of error, between a sample statistic and its corresponding population parameter.
What is sample data consisting of frequencies to test hypotheses about the proportions for a population distribution.
What is the T-statistic used for?
What is to test hypotheses about an unknown population mean, when the value is unknown.
Define Correlation?
What is a statistical technique that is used to measure and describe the relationship between two variables.
How many articles do you need to use for your research paper?
What is 10-15
The distribution of sample means is?
What is the collection of sample means for all the possible random samples of a particular size (n) that can be obtained from a population.
The observed frequency?
Define the Degrees of Freedom.
What is they describe the number of scores in a sample that are independent and free to vary.
What happens in a positive correlation?
What seasons were used in the Chi-square experiment?
What is Winter and Spring.
A sampling distribution is?
In observed frequency each individual is?
What is counted in one and only one category.
Define a t distribution.
What is the complete set of t values computed for every possible random sample for a specific sample size (n) or a specific degrees of freedom (df)
What happens in a negative correlation?
What fruit was used in the Chi-square experiment?
What is apples and oranges.
The law of large numbers states?
What is that the larger the sample size (n) , the more probable it is that the sample mean will be close to the population mean.
The expected frequency for each category?
What is the frequency value that is predicted from the proportions from the null hypothesis and the sample size (n).
What does the t distribution shape look like?
Define Pearson Correlation?
What is it measures the degree and the direction of the linear relationship between two variables.
What type of scale was used to get data in the T-test assignment?
What is a Likert scale.
Sampling error is a?
What is a that a sample typically will not provide a perfectly accurate representation of its population.
The expected frequencies define?
What is an ideal , hypothetical sample distribution that would be obtained if the sample proportions were in perfect agreement with the proportions specified in the null hypothesis.
Confidence interval is?
What is an interval, or range of values centered around a sample statistic.
State 1 way that correlations are used?
Prediction
Validity
Reliability
Theory Verification
